Configuring a new domain
Every year, our free testing domain will expire and we have to move to the next one. We aren't buying a full domain on purpose here, it is a great new admin first task and it expires in the first few days of May.
Pre-rebuild changes
Do these things before running nixos-rebuild switch
- run
rndc -k /etc/bind/rndc.key freeze $olddomain
- Stop bind
- Rewrite
/var/db/bind/$olddomain*
and update the domain name
Nix config changes
- Update the
redbrick.tld
in the host's configuration.nix. - If configured, update the domain details in
services/dns/default.nix
Post-rebuild changes
- Rename
/var/mail/$olddomain
->/var/mail/$newdomain
- Remove
/var/lib/acme/$olddomain
- Run
systemctl start acme-$newdomain.service
- Restart things that depend on certs (httpd, postfix, dovecot, etc)
- Go to the Mailman Django admin page and update the domain name in sites, and clear all queued tasks.
